Abstract
A method, for correcting a rolling shutter phenomenon, includes obtaining a double fish-eye image to be processed using a photographing device; obtaining an image processing parameter including gyro data of the photographing device; calculating a rolling shutter phenomenon correcting parameter based on the image processing parameter; and correcting the rolling shutter phenomenon with respect to the double fish-eye image in a spherical-coordinate system using the rolling shutter phenomenon correcting parameter.
